It certainly will. Bought a 1991 Blue Water boat on an EZ-Loader trailer, loaded the truck with all the camping gear and supplies for two families for five days and headed north to one of our favorite spots East of Colville, WA on Hwy. 20...a 2 1/2 hour drive from our house in Spokane. Pulled down to and held 1200 rpm MOL on several hills without a downshift. Had several 6% MOL grades that called for 3rd hole running. Temperatures in the mid 80's and the idiot temp gauge barely moved off it's usual spot and then not until we got back to in-town driving to the house. No change in oil pressure.

Upon arrival back in Spokane I filled the truck and boat gas tanks and then I weighed the whole outfit minus one passenger and about 200# of supplies used. The truck weighed 5360# and the trailer 3600# total GVW 8960#. MPG of 12.1. No oil usage (5w-30), no coolant usage. Other than getting a bit of a roll from a dead stop in the first hole (granny gear), driving around town was little different than when running empty with upshifts between 1500-2000 rpm and cruising in the top hole on 30 mph streets at about 1000 rpm...no problem.

Engine bored 30 over and fitted with hyper pistons. Mild P/P on head, three angle valve job with 30* back cut and a port match. Head and block milled for truing and clean-up. Offy DP with a Holley 1848-1 465 cfm 4v carb and EFI exhaust manifolds. Comp 260h cam and lifter kit. Mallory HyFire 6a ignition, ACCEL coil, Taylor Spiro wires and NGK EFI spark plugs gapped @ 50. Three-way Cat and a generic turbo muffler all 2 1/2 inch in and out.

Will it pull? Piece of cake.

 

That's awesome! That 300 of yours is a real piece of work (and my inspiration).

I forget though, what trans, tires, and final drive do you have?

 

I too wonder about the final drive ratio and tire size.

 

I am still trying to figure out how many cans of BEER it takes to = 200 pounds

 

Amazing performance for that much weight. My bone-stock EFI will pull a five-mile, 6% grade in fourth, empty except for 200lbs. of toolbox & contents. I've no idea how it would handle almost 9000lbs. on the same grade.

 

I put these postings at FSP here: FORDSIX PERFORMANCE • View topic - Will it pull?

Many :thanks: for the compliments . Everything that went into my build was gleaned from this Forum.

Who can do the math for me on the rear end ratio since I am challenged in that area? 30-32 mph at 1000 rpm on 235/75R15 tires.

Trailer is an EZ-Loader made here in Spokane. It is equipped with surge brakes that work quite well. I have one adjustment to make...move the axle back to transfer some weight to the hitch as the weight distribution is not quite right. The boat engine is a 4.3 GMC ( ops: ) Mercruiser stern drive and hangs out just a bit too far behind the trailer axle for proper handling....getting a slight "tail-wagging-the-dog" between 55 and 60 mph. With the whole set loaded as described the truck and trailer are right at level front to back with no "bow steer" on the truck. My truck weighs 4200# empty with full tanks, a fiberglass topper and me at the wheel.

Northern and eastern WA, the ID Panhandle, and western MT have 5 Star camping and fishing. For our next and last big outing for the year we are considering Curlew Lake in Ferry County or sneaking over to Joe's neighborhood on the Pend Oreille.

Thanks SR. That sounds about right for 65 mph. My speedometer runs out about 2 mph faster than actual ground speed according to the radar reader boards around town and a check between mile markers. BTW it pulls 8-10 hg of vacuum at a 60 mph cruise on the level and no wind to contend with with this load and the cheap narrow band AFR gauge showing stoich/lean. I don't think I need to change a thing as far as rear gear ratio is concerned. I am pleased with the way it runs.

Spent a few hours moving the trailer axle back 6" and the winch stand ahead 2". Reweighed the set though this time my truck was empty...4400# for the truck and 3460# on the trailer. The adjustments moved 140# to the hitch with total hitch weight right now at about 200#...just right. Hitch height went from 19 1/8" to 18 3/4" Tried 'er out on the big road on the way back up to 70 mph...nary a bobble. When I measured everything up before making the adjustments, the axle was 5/8" out of alignment from one side to the other. It's dead-square now and pulls arrow straight.

Shifting goes like this: Just get it rolling in granny with a quick shift to second where it picks up at about 800-1000 rpm. Next upshifts can be done at 1500-2000 rpm. This all depends on the terrain...hard pulls up hill and I might go 2500-3000 rpm before on an upshift. I have pulled it down to and held at about 1200 rpm on some inclines that I'm guessing are between 3% MOL without shifting out of road gear to 3rd.

Hey AB! Maybe you can do the math...30-32 mph at 1000 rpm, 60-61 mph at 2000 rpm. 235/75R15 tires.

I did some 6% grades in the 3rd hole at about 40-45 mph.

There was only a half-rack of beer, 1/2 gallon of R & R and Vodka each on board...but my son-in-law replenished the stash of beer at the resort. Me and drinking got a divorce in 1991...but I did finish off a case of Gatorade over the 5 day period. Most of the weight we shed was probably in eats consumed and firewood we brought along and burned.

 

Sounds like a fun trip! Just got back from something similar with my family last weekend. I love how the 300 pulls up those steep old washed out mining roads in low range 4x4 when everyone else is struggling. Had the oldest rig there, and there were honestly times when I'd get so far ahead that I'd turn the engine off and take a walk around while I waited for them to slowly work their way up.

That sounds like a great trip though, hopefully you took some good pictures.




Were both of those RPM/Speed combos you gave me in 3rd gear?
If so...

Final Drive = (RPM * Tire Diameter) / (Speed * Gear Ratio * 336)

A 235 75R15 is appx: 28.85" in diameter. Weight of the vehicle, tire wear, never as big as they say they are.... 28.5"

@ 30 - 32mph (lets say 31)
Final = (1000 * 28.5) / (31 * 1 * 336)
Final = 2.73

@60 - 61
Final = (2000 * 28.5) / (60 * 1 * 336)
Final = 2.82

Looks like you have a 2.75.

 

Those speeds are in "road gear"...4th in a granny 4 speed...1:1 final transmission ratio. Did get a couple of pics...one of a moose and couldn't get a clear shot but got an excellent pic of a beaver. We were within 12-15 feet of it before diving with the customary tail slap. Brought home a few fish...two nice bass and a number of "keeper" trout. We released quite a few now "educated" trout.

Years ago when back in western NE we had a Bronco with a 170. Loved it for tooling around on the breaks of the N Platt River and in the Sandhills...low range and 4wd...lots of fun.

 

Great post, Harte! Makes me wish my 300 was built.

Think of what you could pull with a 4.10 gear! You wouldn't get the fuel mileage, though.

 

For what I pull and my manner of driving I don't need to change...kinda the "if it ain't broke, don't fix it" theory.

 

I wasn't saying you needed to change. I wasn't even saying you should.

=)

 

hmmm i threw a e350 van on the back of my 88 and she went on down the road just fine its a 88 4.9, 4 speed manual, and a 3.08 open rear

 

...we had a Bronco with a 170. Loved it for...

HHH-
Uhoh, a 250 I6 ('69 'stang) is on it's way here from TN (to Amherst, MA). "A few puffs" and "100,000 mi. on it" from a trusted forum buddy of over 10 yrs. Hope I'm not goin off course. 8-0 ($235 for purchase n shippin was too much to resist even for the unemployed-me).
I don't believe I've been to FSP (in a long time - may B that's where I got the 250 idea? R they the ones w/the X-Flow write ups?). Thanks for the referral. I'll check them out along with the Schjeldahl brothers for assisting this non-mechanic create a low rev torquer. ;-}

 

double post

 

Between FSP and the Schjeldahl bros one can find anything thought of to do with a SB6 that has ever been done. Sounds like you scored a gem of a buy.
